TaxTim says: 2 July 2013 at 9:53 The additional medical deduction is based on a formula of any amount exceeding 7.5% of taxable income. You also need to take your tax credits and multiply by 4, the difference between that amount and what you spent overall plus your out of pocket expenses, if greater than the 7.5% of taxable income will be allowed as a further deduction. It's a very complicated formula and doesn't really favour the taxpayer at all. |
